Question 1

True or false: All IoT devices require a constant internet connection to function properly at all times.

Accepted Answer

False. Many IoT devices, like smart thermostats or sensors, store data locally and sync later. Connectivity isn't always mandatory.

Question 2

True or false: IoT devices always use encryption by default to protect data transmitted over the internet.

Accepted Answer

False. Many cheap IoT devices lack encryption, sending data in plain text. This is a known security vulnerability in the industry.

Question 3

True or false: A smart fridge can automatically reorder milk by detecting its weight and communicating with a grocery app.

Accepted Answer

False. While prototypes exist, most commercial smart fridges lack this ability. They typically just track expiration dates or show internal cameras.

Question 4

True or false: The term 'Internet of Things' was coined by Kevin Ashton in 1999 during a Procter & Gamble presentation.

Accepted Answer

True. Ashton used it to describe RFID tags linking objects to the internet. The term stuck and became the field's foundation.

Question 5

True or false: IoT devices can be infected with malware that turns them into botnets for launching massive cyberattacks.

Accepted Answer

True. The Mirai botnet in 2016 used compromised IoT cameras and routers to disrupt major websites via DDoS attacks.

Question 6

True or false: The average smart home has over 50 IoT devices connected to its network at any given time.

Accepted Answer

False. Surveys show typical homes have 10–20 connected devices. Fifty is an exaggeration, more common in tech-heavy households.

Question 7

True or false: Smart light bulbs can be hacked to reveal your Wi-Fi password by analyzing their power consumption patterns.

Accepted Answer

True. Researchers demonstrated that fluctuations in a smart bulb's power usage can be used to exfiltrate data, including passwords.

Question 8

True or false: Some IoT sensors are powered entirely by harvesting ambient radio frequency energy from Wi-Fi signals.

Accepted Answer

True. Researchers have developed 'ambient backscatter' devices that capture and convert Wi-Fi or TV signals into usable electricity.
